CONTROL MECHANISM FOR MOTOR-VEHICLES.

Specification of Letters Patent.

Application filed September 7, 1909.

To all whom it may concern and State of Michigan, have invented certainnew and useful Improvements in Control Mechanism for Motor-Vehicles, of

which the following is a specification, refer-' ence being had thereinto the accompanying drawings.

The invention relates to control mechanism, and more particularly to themeans for controlling the power transmission in a motor vehicle.

It is the object of the invention to obtain a simple, compact andefl'icient control, and to this end the invention consists in theconstruction as hereinafter set forth.

In the drawingsFigure 1 is a perspective View of a portion of the frameof an automobile to which my improvement is applied; Fig. 2 is a planView thereof; Fig. 3 is a side elevation; Fig. 4 is a section on lineXX, Fig. 2; and Fig. 5 is a detailed sectional view in the plane of theoperating levers.

A is the frame of the motor vehicle, having the parallel side sills Aand the cross frame B, upon which is supported the casing C for thetransmission gearing. The transmission gearing housed within this casemay be of any suitable construction for securing a plurality ofdifferent speeds, and also preferably including a main clutch forconnection with the motor. The operating and controlling devices for themechanism include a push rod D for controlling the main clutch, asliding shaft or bar E for controlling the shiftable gears, and a rockshaft F for controlling other shiftable gears. These three members allproject through bearings in the rear wall of the casing C and arecontrolled by mechanism of the following construction.

G is a rock shaft extending transversely of the frame and journaled inbearings on the opposite side sills thereof. This shaft is preferablyemployed for operating the emergency brake for the vehicle, and to thisend is provided with a rock arm H and a controlling lever I arranged atopposite ends thereof. In addition to its function of controlling thebrake, the shaft G forms a supporting bearing for a tubular rock shaft Jsleeved thereon, having an actuating lever K and a rock arm M, thelatter being connected with the end of the sliding rod E. A stillfurtherfunction for the shaft is that it forms an anchor or support for abearing 0, in which the outer end of the rod F is journaled. Thisbearing 0 has an eye- 0 sleeved upon the shaft G and positioned thereonby collars P P on opposite sides thereof secured by set screws. Belowthe eye portion the bearing 0 has a portion 0 bored at right angles tothe shaft G and forming the journal bearing for the rock shaft F. Thisrock shaft is actuated by a rock arm F arranged adjacent to the j ournalbearing 0 and connected by a link F to the control lever K, which iscapable of moving in a direction longitudinally of the shaft G as Wellas pivotally thereabout. A collar F is arranged upon the opposite sideof the journal bearing and is adjustably posit-ioned by a set screw,while the rock arm F is also adjustably secured by a set screw, therebypermitting the proper alinement of each of the shafts F and G.

The shafts E and F are preferably ar ranged on opposite sides of theaxis of the casing C and in the same horizontal plane. Below the planeof these shafts, is the push rod D, which is actuated by a pedal leverQ, fulcrumed upon a lug It integral with the casing O. This pedal leverextends upward and is arranged for convenient operation in relation tothe footboard of the vehicle.

The construction above described formsa simple, effective andinexpensive means of supporting and actuating the various elements ofthe control mechanism.

What I claim as my invention is:

1. In a control mechanism for motor vehicles, the combination with thevehicle frame, of a rock shaft extending transversely thereof, a secondrock shaft extending longitudinally of the frame, a journal bearing forsaid second shaft pivotally engaged by and supported from said firstshaft, means upon said first shaft for holding said bearing fromlongitudinal movement thereon, a rock arm on said second rock shaftadjacent to said journal, and an actuating link for said rook armmovable in a direction substantially parallel to said first rock shaft.

2. In a control mechanism for motor vehicles, the combination with theframe, of a rock shaft extending transversely thereof,

a tubular rock shaft sleeved thereon, a rock arm secured to said tubularrock shaft, a slidable rod extending longitudinally of said frame, alink connecting said slidable rod with said rock arm, a secondrock-shaft parallel to said slidable rod and extending transversely tosaid first-mentioned rock shaft, a hanger sleeved on said first shaftforming a journal bearing for said second rock shaft, a rock arm on saidsecond rock shaft adjacent to said journal bearing, and an actuatingmember for said last mentioned rock arm movable in a directionsubstantially parallel to said first-mentioned rock shaft.

3. In a control mechanism for motor vehicles, two rock shafts extendingin direc tions transverse to each other, a hanger having portionssleeved upon each of said shafts and held from longitudinal movementthereon, a rock arm on each rock shaft, and an actuating member for eachrock arm movable in a direction longitudinally of the opposite shaft.

4. In a control mechanism for motor vehicles, thecombination withaframe, of a transmission housing secured centrally of the frame, a rockshaft and a slidable rod extending from said housing longitudinally ofsaid frame and substantially parallelly arranged, a transverselyextending rock shaft, a bearing o-urnaled upon each of said rock shaftsand connecting the same together, adjustable means for positioning saidbearings upon said shafts and holding the same from longitudinalmovement, and actuating levers for each of said rock shafts and for saidslidable rod.

5. In a control mechanism for motor vehicles, the combination with theframe including spaced side sills, of a rock shaft Copies of this patentmay be obtained for five cents each, by addressing the Commissioner ofPatents,

member suspended from the first mentioned shaft having transversebearing portions arranged in different planes and loosely sleeved onsaid shafts, adjustable collars on each of the. shafts upon oppositesides of said member for positioning the latter in relation to theshafts, and an actuatinglink pivotally connected to one of the collarson the longitudinally extending shaft.

6. In a control mechanism for motor vehicles, the combinationv with thevehicle frame including spaced side sills, of a rock shaft extendingacross the frame and journaled in said sills, a second rock shaft ex--tending longitudinally of the frame a journal bearing for said secondshaft pivotally said side sills, a tubular rock shaft sleeved upon thetransverse shaft, a rock arm secured to said tubular rock shaft, aslidable rod extending longitudinally of the frame,

a link connecting said slidable rod with said rock. arm, a second rockshaft extending. transversely to the first mentioned rockshaft, a hangersleeved on said first shaft forming a journal bearing for the secondrock shaft, a rock arm on the second rock shaft, and an actuating memberforsaid last mentioned rock arm.

In testimony whereof I aifix my signature in presenceof two witnesses.
